Title:

SURFACE-MODIFIED NANODIAMOND, NANODIAMOND DISPERSION COMPOSITION, AND METHOD FOR MANUFACTURING SURFACE-MODIFIED NANOCARBON PARTICLES

Document Type and Number:

WIPO Patent Application WO/2021/006120

Kind Code:

A1

Abstract:

Provided is a surface-modified nanodiamond having excellent dispersibility in an organic solvent, or a surface-modified nanodiamond as an intermediate for obtaining said surface-modified nanodiamond. Also provided is a method for manufacturing surface-modified nanocarbon particles, whereby various surface-modifying groups can be introduced to nanocarbon particles.　The surface-modified nanodiamond according to the present disclosure includes a nanodiamond particle and a group represented by formula (1) or a group represented by formula (2) for surface-modifying the nanodiamond particle.
